Organic light emitting diodes for polymer based optical waveguide devices

Summary form only given. Organic light emitting diodes (OLED) utilizing fluorescent dyes or conducting polymers have attracted great interest due to their advantage for an emission in the wide visible spectral range, high emissivity and low driving voltage. In the paper, we discuss optical and transmission characteristics of OLED which consist of 8-hydroxyquinoline aluminum and a diamine derivative and of a europium complex and azomethin derivative. We also discuss their transmission characteristics in polymer waveguides.
